Title: Innovations by Chung J Lai in Phosphate Waste Management
Introduction
Chung J Lai is an accomplished inventor based in Placentia, CA (US). He has made significant contributions to the field of phosphate waste management. His innovative approach focuses on the densification of phosphatic wastes and phosphoric acid slimes, which are byproducts of phosphate ore mining.
Latest Patents
Chung J Lai holds a patent for the "Densification of phosphatic wastes and phosphoric acid slimes." This patent addresses the concentration of phosphatic wastes produced during mining and beneficiation processes. The method involves treating slimes with an initial concentration of suspended solids, usually less than about 5%, in a series of crossflow filters. This process can concentrate the solids to 24% or higher. In one embodiment, a series of three spiral-wound crossflow filters followed by a fourth stage tubular crossflow filter is utilized. This setup can concentrate slimes with about 3% suspended solids to a concentrate with 30% or more suspended solids. By maintaining a linear velocity over the filter medium at 5 ft/sec or higher, a high permeation rate is achieved while producing a permeate with an extremely low suspended solids concentration. Proper selection of filter medium and flow rates can yield permeates with a turbidity of less than about 5 Jackson Turbidity Units.
